Overview

Sites built with ACF often keep important content in custom fields: text, images, galleries, relationships and repeaters. Translating that content by hand is slow and easy to get wrong. This extension links ACF to WPML so those fields become part of the normal translation process, and the structure of your custom data stays intact in every language.

Translators work in WPML's familiar translation editor, so there is no separate tool to learn. The plugin works with WPML's core and its other addons, and it supports a wide range of ACF field types, including complex and repeater fields. It fits agencies, developers and businesses running custom-built sites in more than one language.

Features

  • Translate ACF custom fields: Custom fields can be translated alongside the rest of your content, from simple text to complex repeaters, which keeps the experience consistent for visitors in each language.
  • Works with WPML: The plugin runs alongside WPML's core and other addons, giving you one workflow for managing multilingual custom content instead of several disconnected tools.
  • Support for ACF field types: Text, images, galleries, relationship fields and other ACF field types are covered, so translation reaches the full range of your custom content.
  • Familiar translation editor: Translators handle custom fields inside WPML's own translation editor, which keeps the localization process simple for teams already using WPML.
  • Data structure stays intact: The structure and relationships of your custom fields are preserved in every translation, which helps avoid data loss or errors across languages.
  • Automatic synchronization: Custom field groups and settings are synced between languages automatically, which cuts down the manual upkeep on multilingual sites.
  • Built for large content sets: The plugin is designed to work efficiently on sites that carry a lot of custom content and several languages at once.
  • Hooks and filters for developers: Developers get hooks and filters to adapt the plugin's behavior to the specific needs of a project.

Best for

  • Agencies building multilingual sites with ACF
  • Developers translating repeater and relationship fields
  • Businesses running custom WordPress sites in several languages

Changelog

Version 5.2.0 — 21 October 2026

  • Improved Taxonomy custom fields set to Copy are locked on term translations.
